Authors’ summary: An efficient algorithm is developed to compute the dynamics of a magnetized particle in a discrete model of a nonradiative Vlasov plasma. The algorithm is based on the drift approximation of the equations of motion for a charged particle in electromagnetic field. Numerical tests have shown that the proposed algorithm is more efficient than the conventional finite-difference algorithms based on the particles method by one to four orders of magnitude (depending on the degree of magnetization).
